Objective:

To describe a case where escalation of PEEP during one-lung ventilation led to paradoxical hypoxemia due to a pressure-dependent right-to-left intracardiac shunt.

Approach:

Key Findings:

• Remove any implications about clinical practice.

Interpretation:

Revise to focus solely on the case details without unsupported conclusions.

Limitations:

• Intraoperative echocardiography was nondiagnostic due to limited acoustic windows.
• Routine preoperative screening for PFO was not performed in this asymptomatic patient.

Conclusion:

Revise to reflect only the findings of the case without recommendations.
